tatably seated in aperforation intheflattened portion 17 of-the rod 16 and in an opening 21 of a bell-crank lever 22. This lever 22 is arranged upon a vertical axis, and its spindle 23 is extended to and mounted in the bars 5 and 6, whereby the lever is adapted to swing in a horizontal plane. The forward arm of the lever 22 is formed with a hook 24, with which the eye 25 of a pitman-rod 26 is connected.

27 indicates a revoluble shaft which has bearings in the plates 28, secured one to each side of the left-hand portion of the frame 1, while the shaft is held from longitudinal movement by means of a washer 29 and enlarged portion or head 30, the latter being located on the inner end of the shaft and having rigidly fixed thereto or formed integral therewith a crank-disk 31. The outer end of the shaft 27 is squared and provided with a removable crank-arm 32, secured in place by means of a key, and the crank-disk 31 is provided with two openings 33, which are arranged at diiferent distances from the center of the disk and are provided to permit the connection of the link 34 and pitman-rod 26 with the disk. The link 34 has its rear end formed with a trunnion-like portion 35, which fits into one of the openings 33, while the-pitman-rod 26 is provided at its forward end with an eye 36, whichembraces the trunnionlike portion 35, whereby the pitman-rod 26 is connected to the disk 31. Thus it will be seen that as the shaft 27 is revolved in the operation of the churn thecrank-disk 31 will impart to the pitman rod 26 a movement which will be reciprocal at its rear end to swing the bell-crank 22 on its vertical axis. As the bell-crank 22 rocks the link 20-will be reciprocate-d to impart motion to the yoke'16, and hence to the sides 4 of the bellows. The link 34 has its front end formed with a stud 37, which fits into one of the openings 38 of the crank-arm 39, forming a member of a rock-shaft 40, mounted in bearings in the blocks 41, fixed to the inner surface of the The shaft 40;is arranged transversely and is provided at its inner end with an arm 42, which projects through a slot 43 in the front end of the frame to swing in avertical plane as the rock-shaft is operated. The front end of the arm 42 is formed with a stud 44, extending transversely intoan opening in the dasher-rod 45, which reciprocates through an opening 46 in the top 47 of the churn tub or receptacle 48.

The rod 45 carries the dasher 49, which is circular in form and is provided with a series of perforations surrounding a central opening 50, through which extends the air-introducing tube 51, the dasher being guided by said tube. The air-introd ucing tube extends vertically through an opening 52 in the top 47 of the receptacle and terminates at its lower end adjacent to the bottom of the receptacle.

The nozzle 11 of the bellows is extended longitudinally and thence downwardly, and is fitted in, the upper end of the tube 51, so that a blast from the bellows will be introduced into the tube.

58 indicates inlet openings, which are formed, respectively, in the side wal1s4 of the bellows, and are controlled by the clackvalves 59. By hanging them downwardly they are held by gravity in a closed position, which will assist in the effective operation thereof.

60 indicates a top for the frame 1, and this is made to cover the upper side of the frame, so as to hide and protect the mechanism within the churn and at the same time form an unobstructed table-top. The operating mechanism, including the bellows, is arranged within the horizontal frame between the planes of the upper and lower edges thereof, and hence is concealed and protected from accumulations of dust or other injury, and

the table-top 60 being unobstructed is adapted to perform its ordinary function irrespective of the churn mechanism, either during the churning operation or at othertimes. The
